RGB LED Strip Circuit With Arduino: 4 Steps

But it still isn't throwing the solenoid even though it's lighting the LED and has a good 5 Volts. I've switched the relay board back to the 5v device and it works like a champ there. Where do you buy the PCB boards? I looked all over the page but couldn't find it. If I use an arduino board to send the signal to the transistor thru R2

Compact smart relays - Smart Relay - Zelio Logic SR2/SR3

Regarding power, the Arduino requires 5V and the LED string needs 12v. If you want to use one power source, use a 12V power supply to power LEDs directly and use a voltage regulator (7805) before providing power to the Arduino. Step 3 of this instructable shows a diagram and explains this in greater detail. Hope this helps.
